I have an alias like this; it takes commandline parameters just fine:

	alias cd='. $HOME/.ksh/cd'	# CHANGE DIRECTORY, RESET PROMPT

Here's what's in the $HOME/.ksh/cd file:

	\cd $1		# \ MEANS USE REAL cd COMMAND, NOT ALIAS
	cdstat=$?	# SAVE cd STATUS FOR cl ALIAS
	PS1="<`prompt ~ \`/bin/pwd\``,!> " # BUILT-IN pwd CAN'T HANDLE SYMLINKS
	set --		# CLEAR OUT POSITIONAL PARAMETERS FOR NEXT ALIAS

(The "prompt" command is a prompt-generator.)
